Description
This unit specifies the skills and knowledge required to develop two-dimensional (2-D) and three-dimensional (3-D) visualisations in a geographic information system (GIS) or computer-aided design (CAD) context. It includes the application of specialised technical and conceptual skills and a broad knowledge of spatial datasets. The unit also includes the development of technical documentation incorporating mapping and scientific techniques. This unit is suitable for surveyors who use broad theoretical and technical knowledge to analyse information as well as interpret and provide solutions to unpredictable and sometimes complex surveying/spatial information problems. The unit supports those who work in a technical management role in a spatial information services team in areas such as cartography, town planning, mapping and GIS.All work must be carried out to comply with workplace procedures, in accordance with relevant state/territory regulations that govern surveying work, as well as work health and safety(WHS) legislation and regulations that apply to the workplace. Cadastral surveying must be undertaken under the supervision of a registered surveyor. Users must check with the relevant regulatory state/territory authority before delivery. No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1 Prepare 2-D or 3-D digital elevation model (DEM).
  • 1.1 Analyse job specifications, constraints and main work activities.
  • 1.2 Prepare CAD environment by setting up hardware and software systems, drawing defaults and customising menus.
  • 1.3 Design GIS or CAD environment of surface elevation according to project specifications and organisational requirements.
  • 1.4 Establish views and layouts according to job specifications.
  • 1.5 Investigate current remote sensing technologies for capturing raw elevation data.
  • 1.6 Conduct searches to identify available spatial data and evaluate and obtain suitable data to meet drawing specifications.
  • 1.7 Apply organisational requirements relating to working safely when using screen-based equipment.
2 Create 2-D drawings.
  • 2.1 Create detailed views and layouts using various scales according to job specifications.
  • 2.2 Finalise 2-D drawings and modify existing 2-D model as necessary to meet job specifications.
3 Create 3-D model or DEM.
  • 3.1 Model surface elevation by mathematically defined surfaces and by point or line data according to job specifications.
  • 3.2 Determine products that can be derived from a DEM according to job specifications.
  • 3.3 Create and manipulate entities in 3-D space according to job specifications.
  • 3.4 Develop DEM with a range of thematic data and generate and drape profiles over model according to project specifications.
  • 3.5 Create contour map of area by employing procedures appropriate to data format and software according to job specifications.
  • 3.6 Create slope map of area from gradient and aspect components according to job specifications.
  • 3.7 Create shaded relief map of area from gradient and relief map representations according to job specifications.
  • 3.8 Finalise 3-D drawings and modify existing 3-D model as necessary to meet job specifications.
4 Produce output.
  • 4.1 Apply quality and accuracy measures on modelled 2-D and 3-D outputs.
  • 4.2 Document 2-D and 3-D outputs according to project specifications and organisational requirements.
  • 4.3 Save drawing files and elevation data outputs in appropriate format according to job specifications and organisational requirements.
  • 4.4 Extract physical properties to job specifications and use slope map of area for analytical purposes.
